I will just say, I went with a Yamaha RX-V2300 for my set-up. I had a Denon, but it would not handle 4 ohm loads (which you must watch), and the QS8's are. Power wise its killer, and its options are very good. I picked it over Marantz at the time. If your looking for a music reciever I would say consider the Marantz, but for Home Theater, which I use mine for 95% of the time, it was the way to go. The Marantz and Denon did not have as many hook-ups in the rear either. I am a all fiber optic/Component video guy for everything possible! lol Yamaha was able to suport me. Have fun!! The search is half the fun!

Ohh Might add my system for comparison! lol
